Specification of Letters Patent.

Application filed October so, 1913. Serial No. 798,165.

To all whom it may concern Be it known that we, CLAUDE J. DUNCAN and ORVIL F. DUNCAN, citizens of the United States, residing at Gridley, in the county of Cofl'ey and State of Kansas, have invented certain new and useful Improvements in Feeders; and we do declare the following to he a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Our invention relates to improvements in feeders for hay presses, and has for its ob-- ject to provide a feeder in the nature of a belt conveyer, whereby material is conducted to and delivered into the hopper of a hay press to be compressed and baled.

It is also an object of the invention to pro- I vide means for simultaneously stopping the feeder and swinging a header block into position for projection into the hopper.

In accomplishing these objects we have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein Figure I is a erspective view of a hay press equipped with a feeder constructed in accordance with our invention. Fig. II is a side elevation of the feeder, showing a portion of the hay press in transverse section. Fig. III is adetail perspective of a'portion of the hay press and feeder, showing the position of the feeder prongs at the point .of delivering hay into the hopper and the mounting of theheader pan. Fig. IV is a rear perspective view of a portion of the hay press, parts being broken away to show the action of the feeding prongs and cleaning fingers. Fig. V is an enlarged detail perspective of the clutch. Fi VI is an enlarged detail perspective of the lower end of the feeder, the mounting for the header pan and clutch controlling lever. Fig. VII is a detail section of the feeder belt adjustment. Fi VIII is a detail perspective of a portion of the conveyer, showing the means for attaching the rake bars to the driving chains, and for tensionin the feeder prongs.

Referring more in detai to the drawings 1 designates a hay press of any ordinary construction, comprising ground wheels 2, a

' frame 3, feeder arm l, header'block 5, hop-- per 6, and driving gear 7 the latter comprising a shaft 9, which is revolubly mounted in bearings 10 on the frame and carries a fiywheel 8 and belt wheel 11. A pinion 12 mounted on the end of the shaft 9 opposite the fly-wheel meshes with a large gear wheel Journaled inbrackets 19 on the frame 3,

at one side of the hopper, is a shaft 20, and pivotally mounted on'the shaft is a feeder frame 22 comprising inclined sills 23 hav ing feet 24 at the lower end whereby the frame is supported from the groundandcomprising a longitudinal platform 25 and Sprocket wheels removable Sideboards '26. 29 are revolubly mounted on the shaft 20 and sprocket wheels 30 on, a shaft 31 at the free end of the feeder frame, and running over said sprocket wheels are link belts 28 upon which the feeding rakes hereinafter described are mounted.

In order to tighten or adjust the conveyer belts, we project the ends of the shaft 31 through slots 39 in the lower ends of the sills 22, and project bolts 33 through the ends of the sills and through threaded apertures in the ends of the shaft 31, so that when the heads 34 of the bolts 33 are turned the shaft 31 is drawn outwardly, or forced inwardly to tighten or loosen the conveyer belts.

At intervals throughout the length of the belts 22 are links as (Fig. viii having transverse apertures within which the cross bars 37 are revolubly-mounted, and fixed in said cross bars are rake teeth 38, which are adapted for projection into the conveyer frame and for forwarding material'within the frame when tion.

In order to allow the rake to revolve in its bearings, so that it may be withdrawn from the hopper after delivering material thereto and to return to functional position, We provide the links 36 with slots 40 and the rake bars 37 with teeth 39- corresponding with theiteeth 38, but which areprojected the apparatus is in opera- Patent-ed Oct. 2c, 1914.

through the link slots lOand are engaged by springs-4:1, which are mounted on the rake bars and are adapted for yieldingly tensioning the bars to functional position but allow the bars to yield when the rakes engage the edge of the frame as they are turned backwardly beneath the conveyer after delivering material into the hopper.

The frame 3 is provided with fingers 4A, which project upwardly therefrom at the inner end of the com eyer and between which the rake teeth travel after the latter moves back over the'conveyer, in order to clean the rakes of material and insure the delivery of the complete charges into. the hop )er.

The mechanism for operating the conveyer belts, comprises a bevel gear a6 on the forward end of the upper conveyer shaft 20, which meshes with a bevel gear 47 that is revolubly mounted on an inclined shaft i8,

that is journaled in brackets 49 and 50 on' the main frame 3, and is operably connected with the driving shaft 9 through bevel gears 52 and 53, a shaft 5i carrying the bevel gear 53, and the gear wheels 55 and 12.

Slidably mounted on the shaft 48 and keyed against revolution thereon by the feather 57 is a clutch 58 having a shipper groove 59 and having clutch teeth 60 and (31 thereon adapted for engagement with the teeth 62 and 63 on the collar (Bl ofthe bevel.

gear 47, so that when the clutch members are in engagement and the driving mechanism in operation the conveyer shaft is revolved to forward the rake teeth toward the hopper; the clutches being arranged to engageat a proper point in the revolution of the shaft 48, so that the rakes may operate in proper relation to the up and down movement of the-feeder arm.

Pivotally mounted in a bracket 65 on the frame 3 is a shipper lever 66 having arms 67 operatively connected with the grooved portion of the clutch 58, and connected with said lever is a rod 69 which extends beneath the conveyer frame and is pivotally connectedwith an arm 70 on a rod 71 that extends longitudinally along the conveyer frame and, is journaled in brackets 72 and 73thereon. Fixed on the lower end of rod 71 is a clamp 73 and ,pivotally mounted in said clamp is a. lever 74, which projects through a slot 75in a keeper member 76 that is fixed on the lower end of the conveyer frame; the inner end of the slot 7 5 having an inwardly offset portion forming a seat for the lever 74. Pivotally connected with the lever 7 4 is a rod 78, which extendsinwardly and is pivotally connected with an arm 80 on a pivotally mounted header pan 81.

The header pan which we prefer to use comprises a grooved frame 82 which is hingedly mounted on a standard 83 at the outer ing end of the hopper, so that the pan may move inwardly and outwardly relative to the hopper to bring the header blocks 5 into position for projection into the baling case when engaged by the descending arm 4.

In order to force material from the hopper into the baling case we provide the feeder arm with a shelf 85, which is hingedly mounted on the arm, and has a spring 86 yieldingly retaining the same against a horizontal shelf 87 that is rigidly mounted on the forward face of the arm.

In using the feeder, presuming the parts to be constructed and assembled as described, when the driving mechanism is in operation and the clutch members on the shaft is in engagement, the conveyer belts will be carried upwardlv through the conveyer frame and the rake teeth projected at right angles to the platform .by means of the springs 41, so that material delivered into the conveyer is fed through the -con-. veyer frame and into the hopper of the baling press. As the rakes turn over the end of the conveyer into the hopper they, deliver material to the hopper and then engage the upper edge of the frame 3;

the engagement of the teeth with the frame causing the rake bar to pivot in its mounting against the tension of the springs 41, so

that the rake teeth are Withdrawn horizontally from the hopper and pulled through the material instead of turning circumferentially, thereby obviating any tendency to drag the material out of the hopper as the rakes start back beneath the conveyer. When a sufficient quantity of material has been fed into the conveyer to make up a bale,-

the operator moves the lever 74 laterally away from the conveyer and thereby re leases the lever from its keeper and simul-f taneously rocks the arm 70 to disengage the sliding clutch member from its mate,

and thereby interrupt the driving action of the conveyer. After the conveyer has been" stopped by lateral movement of the lever, the lever is drawn back through the slot '75 to turn the header pan over and across the baling case at the back of the hopper;

the driving member continuing to operateafter the conveyer has been stopped, forcthe feeder arm 4L downwardly, so that it engages a header bloc; 5, which is carried in the pan and forces the block out of the pan into the baling case. After the block has been placed the conveyer is again started in operation, so that material is again fed to the hopper and the operation;

heretofore described continued.
